' Leners Patent N 97,204, dated November 23, 1869.

y- IMPRovED CAR-REPLACER The Schedule referred to in"these Letters Patent and making parl: cf the name.

To all whom it may concern B e it known that 1, BENJA'MIN S. LAWSON, ot' New York, in the county of New York, and State of New York, have invented a new and valuable Improvement in Portable RailwayFrogs; and I do hereby declare that the following isa full, clear, and exactdescription of the construction and operation of the san-le, reference being had to the annexed drawings, making a part of this specitication, and to the letters and tigures of reference marked thereon.

Figure l, of the drawings, is a plan `:iew of my in-` vention, t

Figure?. is a cross-section of the same, through line X X.

Figure 3 is a longitudinal sect-ion of the same,through line Y Y. i My invention relates to street-railways; and consists, niainly, in the construction of and novel arrange- Inent ot' devices in a portable rai|way-frog, whereby the wheels of a street-car thrown oli' the track can be readily guided back upon the rails.

The letter A, of the drawings, designates the rail of a street-railway.

B 'represents the portable frog, a plate o'f castor malleable-iron, trapezoidal in its general shape, and having its inolining sides ilanCIred, as at C and D.

The inner lanch, C, is ibrxned to hook over or catch on the inner side ot' the rail, to prevent the frog from being thrown ott when the wheel comes against the hevelled hase H.

The outer anch, D, yis formed to correspond with the anch of the car-wheel, and to guide it to and on the rail.

The small bevelled end G fits the rail in such a manner that when the oar-wheel reaches it and rolls off, it continues across lthe rail, and falls into its proper position.

The frog is prevented from being tilted by the pressure of the wheel on the bevelled base lH,.by the extension of' the inner anch, and of Aa portion, I, of' theplate adjoining, to the rear, so that the wheel will tirs-t touch the bevelled base at a point forward ot' its bearings. t Y As the frog is bevelled and anched. alike on each side, it can be used on either side ot' the track by turning it over. v

What I claim as my'invention, and desire to secure Witnesses:

E. MILLER, ALEX. MAYER.
